The submitted voltage limiter consists of the insulating shell (26), closed from the top by the electrically and thermally conductive first contact plate (2) provided with the first connecting point (1) and from the bottom by the electrically and thermally conductive second contact plate (10) provided with the second connecting point (9). The embodiment of the two triggering semiconductor elements (5, 13) oriented in opposing directions and the protection member (17) connected to it in parallel, located between the two inner plates (3, 11), is located inside the insulating shell (26). The semiconductor elements (5, 13) are simultaneously interconnected with the electronic control device and connecting points (1, 9). The limiter is equipped with compressive construction to provide clamping and electrical interconnection of individual parts. The first triggering semiconductor element (5) is located between the thermally and electrically conductive first inner plate (3), which is in contact with its cathode (7) and the first contact plate (2), which is in contact with its anode (6). The second triggering semiconductor element (13) is located between the thermally and electrically conductive second inner plate (11), which is in contact with its cathode (15) and the second contact plate (10), which is in contact with its anode (14). The electronic control device may be located outside or inside the insulating shell (26) and consists of the first control device (4) interconnected with the control electrode (8) of the first triggering semiconductor element (5), the first contact plate (2) and the first inner plate (3) and interconnected with the control electrode (16) of the second triggering semiconductor element (13), with the second contact plate (10) and the second inner plate (11) from the second control device (12).
